1998 Ford F-250 Lariat 5.4L Int High Idle
This PU came in the 1st time showing part throttle on the scanner w/throttle closed. Unplugged the TPS and it idled down, so I replaced the TPS. The second time it came back after about 3 days w/same problem & multiple codes. I called 'Diagnostic Hotline',...
